HAT-PIN GUARD.

certain new and useful Improvements in Hat-Pin Guards, of which the following is a specification. e

My invent-ion relates to improvements in hat pin guards, the object of the invention being to provide improved means for protee-ting the point of the pin, preventing accidents and rendering easy the placing in position of the guard and removal of the guard, yet holding securely when in place.

A further object is to provide an improved hat pin guard which clamps upon the pin, and which if a strain is had upon the pin to withdraw it from the hat will allow the escape of the pin without injuring the hat.

A further object is to provide a device of this kind of extreme simplicity, cheapness to manufacture and which can be used with any -form of bat pin.

With these and other objects in view, the

invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and the claim.

In the accompanyin p, drawings: Figure 1, is a broke'n 'view in elevation illustrating my improvements. Fig. 2, is a view in longitudinal section Fig. 3, is an enlarged viewin section on the line 3-3 of Fig. 1, and Fig. 4-, is 'an enlarged view in section .on-the line -1.4 of Fig. 1.

I 1, represents an ordinary hat any ordinary head 2 at its other end.

3, represents my improved guard which is in the form of a tube of spring metal'having a head 4 thereon which may if desired correspond with .the head 2, and said head 4 may be fixed to the tube or removable there One form of removable head is shown in which the head is pro vided with a. screw-threaded shank 5 to screw into the threaded end of tube Tube 3 is provided at oppositesides with slots 6 pointed out in ---and 7 respectively, which extend to the free end of the tube. It will be noted that the I Specification of Letters Patent. Application filed January 19,1911.

pin having 7 Patented Aug. 22, 1911 Serial No. 603,423.

slot 6 is appreciably longer than the slot 7 and herein, lies the most essential feature of my invention. By reasonot these slots, the metal between the slots comprises spring clamping jaws which, due to the different lengths of slot, not only exert a transverse clamping action, but also a torsional onel The strength of the spring is increased over a device having slots of a length equal to the lengthof the longer slot, and the action is different from the action of a tube having slots of the same length.

It is simply necessary to insert the pointed end. of the pin 1' into the tubular guard and force the latter onto the pin when the guard will securely clamp itself in place. If a pull is had on the pin before the guard ,isremoved, the contact with the guard with the hat will enable the pin to be drawn out of the guard and not injure the hat as would be the case if the connection were in any sense a permanent one, but the torsional spring action .of the tube is sutficientto maintain the guard in place without any danger of accidental movement.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

Having thus described. my invention, what I claim as new and desire to secure by Let-tersPatent is:

A hat pin guard comprising a clamping member consisting solely of a tube of spring metal having longitudinally disposed diametrically opposite slots extending from one end thereof, said slots being of differentlengths and both slots being of a width appreciably .less than the internal diameter of the tube,'substantially as described.

In testimony whereof I have signed my name to this specification in the presence-of two subscribing witnesses.
